To all 'LU/0m it mag/,concern Be it known thatI, VILLYAM a a citizen of thel United States, residing in the city of Chicago, in the county of Cook` to the accompanying drawings, forming a 10 part thereof.

The purpose of vide an improved detail construction for an instrument` drive connection inamotorvej hicle. It consists in the elements and fea` tures of construction shown and described, as indicated in 'the claims. a

In the drawingsz-d f j Figure 1 is aplan view of the chassis of a motor vehicle which `is equipped with this invention. j o l a l j Figurev 2 is a partly sectional plan view of a portion of the transmission casing propeller shaft and housing comprising the parts with which the features constituting `this invention areconnected,v` section being made radially of a propeller shaft. j

Figure 3 is a detail section ina horizontal plane in part axial with respect to the propeller shaft casing, and in part axial with o respect to the journal bearing of the driven shaft concerned in the invention.

Figure 4 is a section at the line, l-t, on Figure 3, with the propeller shaft in place, but disregarding the Obliquity of the section with respect to the shaft axis. j

a In respect to the general automobile construction the drawings `show the parts in familiar form withrela'tion to it. A is the transmission casing,` A1 the transmissionv 4U casing memberof the universal joint junc tion between the transmission casing and the propeller shaft housing. B is vthe spheroidal member of the universal joint pertaining to the propeller shaft housing of which C is a continuation which constitutes a ferrule for securing the pipe D1, which constitutes the continuation of the propeller shaft casing. E is the propeller shaft. The

two members, 'C andfD, -of the propeller- `pocket having a journal bearing thereshaft-housing member of the universal joint are secured together in the customary manner by bolts, c, to the mated` lugs, c1 and (Z1. P, P, are braces which extend from 'the mem# ber, D, divergently rearward to the rear H. Solarium,

'this invention isto pro-` axle.` K is asteel bushing 'whichfaffords' journal bearing for the propeller shaft. E1 is a spiral or twist gear cut in the propeller "shaft, Immediately ladjacent to the poa sitionof this gear, the member, D, ,is provided with a laterally positioned exteriorly protruding gear housing,F, constituting a pocket with respect to the part, D, the propeller shaft housing, D1, being apertured to registe'rwiththe opening in said pocket as `seen `at This pocket protrusion, F, has its axis offset laterally below the shaft,

E, and extends forward obliquely with re/ spect to said shaft, as seen clearly in Figure 2. LTlieentrance to this pocket is interiorly threaded, the interior diameter of the thread 'being suiiicient to admit into the pocket a i gear, Gr, adapted to mesh with the gear,` E1,

on theshaft, E, said gear, Gr, being made fast on its shaft, H, the shaft being jour` naled in the plug, J, which constitutes a closure `for thepoclret,` being threaded for screwing into the vinteriorly screw-threaded `mouth or-entrance to the pocket, as seen at y', and outwardly from the iange, J1, which affords a shoulder for `screwing the closure member, J, tight into 'the interiorly threaded mouth of the pocketmember, F; andsaid closure member is reduced in diameter and exteriorly threaded as seen at y'z, for receiving the terminal ferrule, L, of the casing of y a iexible shaft, L1, whose rotating member, 'N, is adaptedv for driving connection with,`

the outer end of the shaft journaled in the closure member, as seen aty a. Theliexible shaft is designed to extend 'to an instrument` "to be driven'which may be understood to be `mounted upon the dash-board, `as conventionally shownfin Figure l.

I ,In a motor vehicle, an instrument drive connection comprising 'the propeller shaft housingmember of` a universaljoint between `said shaft` housing and the transmission casing, said member having `a i gear pocket situated laterally of the propeller shaft the axis of said pocket extending forwardly and lobliquely with respect tothe shaft; a gear cut in the shaft at the entrance to said pocket; a screwed-infclosure for said through; `a shaft journaledy in said closure journal bearing; a gear on the inner end of said shaft meshing withthe gear onthe propeller shaft; said closure being exteriorly formed for attachment thereto of a anuncis, #Aj CORPORATION or casing/fof' flexible; Share ana the Shaft journaled therein `loeng exteriorly Y formed for coupling to the rotary member of the flexible sii-efe; .l l
